# What Is SEO (Search Engine Optimization)? The Complete Guide

Learn what SEO is, how crawling, indexing, and ranking work, the technical and editorial pillars, and how to track traditional search alongside AI answers.

[**SEO (Search Engine Optimization)**](/en/resources/glossary/seo) is the set of techniques applied to web pages to help Google and other search engines understand the content and improve their presence in results for relevant terms. It is not magic, a hack, or a black box: it is a technical and editorial process with a well-defined logic.

The landscape has changed considerably over the past two years. With the arrival of Google [AI Overviews](/en/resources/glossary/ai-overviews), organic CTR fell 61% in affected categories, according to a [September 2025 study by Seer Interactive](https://www.seerinteractive.com/insights/aio-impact-on-google-ctr-september-2025-update). The same study shows a 68% drop in paid CTR for the informational and educational queries analyzed between June 2024 and September 2025. In the third quarter of 2025, brands cited in AI Overviews had 35% higher organic CTR and 91% higher paid CTR than brands not cited. This comparison between groups is not equivalent to an increase in a brand’s clicks over time and does not prove causality.

This guide covers everything: what SEO is, how search engines work, the three technical pillars, what has changed with generative search, how SEO relates to [GEO](/en/resources/glossary/geo) and [AEO](/en/blog/what-is-aeo-answer-engine-optimization-the-complete-guide), and what to do in practice in 2026 in the Brazilian context.

## Key points

- SEO improves access, understanding, and organic visibility; no optimization guarantees indexing or the top spot.
- Technical SEO, on-page content, and external reputation are complementary areas of work.
- Crawling, indexing, and ranking are different stages and need to be diagnosed separately.
- AI Overviews and AI Mode retain SEO fundamentals; citations and business results require their own monitoring.
- Prioritize blocking issues, audience questions, verifiable content, and ongoing page reviews.

## What Is SEO

SEO stands for Search Engine Optimization. In practice, it means making pages readable, relevant, and trustworthy in the eyes of Google’s algorithms—and, increasingly, the AIs that answer questions directly.

The central goal is simple: appear on the first page when someone searches for something related to your business. Position matters a lot. The first position on Google gets 39.8% of clicks, the second gets 18.7%, and the third gets 10.2%, according to data from [First Page Sage](https://firstpagesage.com/reports/google-click-through-rates-ctrs-by-ranking-position/). From the fourth position onward, traffic drops exponentially.

| Google Position | Average CTR |
| --- | --- |
| 1st position | 39,8% |
| 2nd position | 18,7% |
| 3rd position | 10,2% |
| 4th position | 7,4% |
| 5th position | 5,1% |

This is not about being visible in just any way. It is about being in the right position, for the right person, when they are searching.

### What SEO Is Not

SEO is not buying positions on Google. Paid results (Google Ads) appear before organic results and have a “Sponsored” label—they are not SEO.

SEO is not keyword spam, either. Repeating a keyword 50 times in a text has not helped anyone rank well since the mid-2000s. Google is much more sophisticated: it understands intent, context, authority, and quality holistically.

And SEO does not deliver immediate results. According to the [Google SEO guide](https://developers.google.com/search/docs/fundamentals/seo-starter-guide), changes can take anywhere from a few hours to several months to appear. The timeframe depends on the issue, the site, and the competition; not every change produces a noticeable improvement. Assess trends and cumulative effects without promising a fixed timeframe.

### SEO vs. SEM

SEM (Search Engine Marketing) is the term that encompasses both SEO and paid search advertising. SEO is the organic part—with no cost per click. Google Ads is the paid part. Here’s the difference:

| Criterion | SEO | SEM (Paid) |
| --- | --- | --- |
| Cost per click | Zero | Paid per click |
| Speed of results | Months | Hours |
| Sustainability | High (cumulative) | Low (stops when the budget runs out) |
| User trust | High | Lower (perceived as an ad) |
| Scalability | High over time | Linear with investment |
| Position control | Indirect | Indirect (auction, bid, and quality) |

The two are not competitors. SEO and paid media can complement each other, depending on budget, [search intent](/en/resources/glossary/search-intent), and goals. It comes down to the time horizon: those who need results in 48 hours use SEM; those thinking 12 months ahead build SEO.

### SEO vs. CEO

This confusion comes up more often than you might think. CEO (Chief Executive Officer) is a company’s top executive. SEO is the discipline of search engine optimization. They have nothing to do with each other beyond having three similar letters.

The confusion often arises when someone types “CEO” when they mean “SEO”—or genuinely doesn’t know the acronym. If you got here that way: SEO is what you were looking for.

## How Search Engines Work

Before optimizing anything, it’s worth understanding what Google actually does. The process has three distinct stages: [crawling](/en/resources/glossary/crawling), [indexing](/en/resources/glossary/indexing), and ranking.

### Crawling

Google uses automated robots called crawlers (or spiders) to discover pages on the web. The main one is [Googlebot](/en/resources/glossary/googlebot). It follows links from one page to another, mapping existing content.

Not all pages are crawled at the same frequency. Sites with more authority, more frequent updates, and better technical structure receive more visits from Googlebot. If the bot cannot access a page—because of a server error, a block in [robots.txt](/en/blog/robots-txt-for-ai-which-bots-to-allow-and-how-to-configure-it) or too many redirects—Google may not be able to read its content. A URL blocked in [robots.txt](/en/resources/glossary/robots-txt) can still appear in search if discovered by other means; blocking crawling is not the same as using [noindex](/en/resources/glossary/noindex).

### Indexing

After crawling, Google decides what to store in its index—the vast database that search results come from. A page can be crawled without being indexed for several reasons: duplicate content, low quality, a noindex instruction in the code, or simply insufficient relevance to the algorithm.

Having a page indexed is necessary, but not sufficient, for ranking. It is the first filter.

### Ranking

Ranking is where things get more complex. Google uses hundreds of signals to decide which page appears in which position for each search. The most relevant in 2026:

-   Content relevance to search intent
-   Content quality and depth
-   Signals of page relevance and reputation, including link analysis
-   Technical page experience (speed, mobile, [Core Web Vitals](/en/resources/glossary/core-web-vitals))
-   Trustworthy content characteristics associated with [E-E-A-T](/en/resources/glossary/e-e-a-t): Experience, Expertise, Authoritativeness, and Trust; E-E-A-T is not a specific ranking factor
-   [Structured data](/en/resources/glossary/structured-data) ([schema markup](/en/blog/schema-markup-for-ai-visibility-the-7-types-that-matter-and-how-to-implement-each)) describes the content and may enable eligible presentations; it does not guarantee a higher position

Google’s algorithm is not public, but years of testing and correlational studies reveal which factors carry more weight. One concrete example: pages in Google’s first position have, on average, 3.8 times more [backlinks](/en/resources/glossary/backlink) than pages in positions 2–10, according to [Backlinko](https://backlinko.com/google-ranking-factors). The observed association does not prove that acquiring a specific number of links causes a particular ranking position.

## The Pillars of SEO

SEO is not a single technique. It is a set of practices divided into three pillars, each with distinct and interdependent responsibilities.

### Technical SEO

Technical SEO is the foundation of the house. Without it, no content or external link can solve the problem. It covers:

-   **Crawlability:** the site allows Googlebot to find and access all important pages.
-   **Indexability:** the right pages have an indexing signal. Duplicate or valueless pages have noindex.
-   **Speed:** loading time measured by Google’s Core Web Vitals—[LCP](/en/resources/glossary/lcp-largest-contentful-paint), [CLS](/en/resources/glossary/cls-cumulative-layout-shift), and [INP](/en/resources/glossary/inp-interaction-to-next-paint). Good metrics help the user experience but do not guarantee a position; relevance and quality also matter.
-   **URL structure:** clean, short, descriptive URLs.
-   **XML [sitemap](/en/resources/glossary/sitemap) and robots.txt:** files that guide crawlers.
-   **HTTPS:** secure protocol. Without HTTPS, Google flags the site as insecure.
-   **Mobile-first:** since 2019, Google has indexed and ranked sites based on their mobile version.

Technical issues are silent. A misconfigured [canonical](/en/resources/glossary/canonical) can cause two pages to compete with each other in search. A long redirect chain can waste “link juice.” Identifying and fixing these issues is the work of technical SEO.

### On-Page SEO

[On-Page SEO](/en/resources/glossary/on-page-seo) covers everything that happens within your pages: the content, structure, and signals for the algorithm.

-   **Keyword research:** identify which terms your audience uses, their search volume, and their intent.
-   **Title and meta description optimization:** what appears in search results. The title influences rankings; the meta description influences CTR.
-   **Heading structure:** H1, H2, H3 organize content hierarchically and logically.
-   **Content:** depth, originality, and real usefulness. Google favors content that solves the searcher's problem.
-   [**Internal links](/en/resources/glossary/internal-links):** connections between pages on the same site that distribute authority and help crawlers.
-   **Image optimization:** descriptive alt text, appropriate file size, modern format (WebP).
-   [**Schema markup](/en/resources/glossary/schema-org):** structured data that helps Google understand the type of content on a page.

On-Page SEO answers the question: “Does this page deserve to appear for this search?”

### Off-Page SEO

[Off-Page SEO](/en/resources/glossary/off-page-seo) is your site's reputation in Google's eyes, measured mainly by external links pointing to it (backlinks).

A backlink from a high-authority site is like a vote of confidence. The more votes from relevant, trustworthy sources, the greater the [domain authority](/en/resources/glossary/domain-authority). This translates into an ability to rank for more competitive terms.

Beyond backlinks, other off-page signals are gaining weight:

-   Brand mentions (even without a link)
-   Reviews on external platforms (Google Business Profile, Trustpilot)
-   Social media presence (an indirect signal, not a direct ranking factor)
-   Press coverage and digital PR

Link building—the work of earning backlinks—remains one of the highest-return investments in SEO. But quality always beats quantity: a single link from a leading publication is worth more than 500 links from irrelevant sites.

### E-E-A-T: the bridge between SEO and AI

E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) brings together criteria for experience, expertise, authority, and trust used in Google's quality assessments, especially for topics such as health, finance, and safety. The [helpful content documentation](https://developers.google.com/search/docs/fundamentals/creating-helpful-content)clarifies that E-E-A-T is not, by itself, a specific ranking factor.

The “E” for Experience was added in 2022: Google now distinguishes between someone who writes about a topic generically and someone who writes from real experience. An article about recovering from surgery written by someone who has had the surgery has a different value from text generated without any firsthand experience.

Why does this matter for AI? Authorship, evidence, and verifiable sources help assess content reliability, including when it is used in an answer. This does not mean that [ChatGPT](/en/resources/glossary/chatgpt), [Perplexity](/en/resources/glossary/perplexity), and Google AI Overviews use the same E-E-A-T score or publish identical selection criteria.

## What changed in SEO with generative search

Generative search has changed how users interact with results. Previously, Google listed links and users clicked them. Now, Google answers directly—and links appear below the answer or less prominently.

### AI Overviews and their impact on organic CTR

The data is clear and deserves attention. According to [Seer Interactive](https://www.seerinteractive.com/insights/aio-impact-on-google-ctr-september-2025-update), in categories affected by AI Overviews:

-   Organic CTR fell 61%
-   Paid CTR fell 68%
-   In the third quarter of 2025, cited brands had 35% higher organic CTR and 91% higher paid CTR than uncited brands; this is a comparison between groups in the sample

These are different comparisons: the decline reflects the change in queries over time, while the [citation](/en/resources/glossary/ai-citation) advantage compares cited and uncited brands. A citation can provide exposure and a path to the site, but the study does not prove that it causes trust or click growth for any brand.

Additionally, 52% of sources cited in Google's AI Overviews come from the organic results top 10, according to [AIOSEO](https://aioseo.com/seo-statistics/). This proportion applies to the cited sample and is not a universal requirement. For AI Overviews and [AI Mode](/en/resources/glossary/ai-mode), the [official Google guidance](https://developers.google.com/search/docs/appearance/ai-features)requires indexing and snippet eligibility, with no minimum ranking position or special schema.

### SEO still works—but the proof is new

The narrative that “SEO died with AI” is not supported by the data. What changed is the distribution of attention and clicks for certain types of queries. The cited studies do not directly measure a category of “mediocre SEO”; the effect varies by intent, industry, results shown, and whether a citation is present.

The proof has changed. SEO success used to be measured in clicks. Now it's measured in:

-   Citations in AI-generated answers
-   High-intent traffic that goes beyond the automated answer
-   Brand recognition generated by exposure in AI Overviews
-   Perceived authority among users who see your brand cited by Google or ChatGPT

### What stopped working with generative AI

Some practices that worked reasonably well before 2023 are rapidly losing relevance:

-   **Shallow content for volume:** articles that simply summarize what others have already said, without an original perspective. AI does this better and faster.
-   **Modern [keyword stuffing](/en/resources/glossary/keyword-stuffing):** filling text with keyword variations without real content depth.
-   **Low-quality link building:** links from generic directories, paid article sites, or low-quality private networks deliver diminishing returns.
-   **Thin-content pages at scale:** creating hundreds of pages with little useful information, hoping one will rank.

What is becoming more important: original data, perspectives from people with real experience in the subject, and content that AI cannot generate on its own because it depends on access, firsthand experience, or an author's perspective.

## SEO, GEO, and AEO: how they relate

With AI systems proliferating and answering questions, two new terms have gained ground: GEO ([Generative Engine](/en/resources/glossary/generative-engine) Optimization) and [AEO](/en/resources/glossary/aeo) ([Answer Engine](/en/resources/glossary/answer-engine) Optimization). They do not replace SEO—they are layers that rely on an SEO foundation to exist.

### SEO is the foundation; GEO and AEO are the layers above it

[GEO](/en/blog/what-is-geo-generative-engine-optimization-complete-2026-guide) is the practice of optimizing content to be cited by generative search engines such as Google [Gemini](/en/resources/glossary/gemini) and AI Overviews. Princeton researchers reported in 2024 that GEO techniques increased visibility by up to 40% in the experimental setting they evaluated, according to the [study published on arXiv (KDD 2024)](https://arxiv.org/abs/2311.09735).

[AEO](/en/blog/what-is-aeo-answer-engine-optimization-the-complete-guide) focuses specifically on direct-answer engines such as ChatGPT and Perplexity, structuring content to answer questions clearly and be retrieved by these systems.

The three are interdependent. See how [SEO and GEO work together in practice](/en/blog/geo-vs-aeo-vs-seo-what-s-the-difference): SEO improves crawling, understanding, and organic presence. GEO aims to improve [retrieval](/en/resources/glossary/information-retrieval) and citations in generative answers. AEO organizes direct, accessible answers. None of these practices guarantees indexing, ranking, or selection by AI.

### Comparison table: SEO vs GEO vs AEO

| Criterion | SEO | GEO | AEO |
| --- | --- | --- | --- |
| Goal | Rank in the organic index | Be cited in AI-generated answers | Be the direct answer in answer engines |
| Mechanism | Relevance, authority, technical factors | Authority, clarity, structured data | Question-and-answer structure, schema |
| Metric | Position, CTR, organic traffic | Citations in AI Overviews, AI visibility | Appearance in featured snippets and direct answers |
| Helpful factors | Relevant content, links, and technical accessibility | Sources, originality, and clarity | Clear answer, accessibility, and evidence |
| Timeframe | Varies by site and query | Varies by engine and data collection | Varies by format and query |
| Relationship | The foundation of everything | Depends on SEO | Depends on SEO and benefits from GEO |

## SEO in Brazil in 2026

The Brazilian market has specific characteristics that affect how SEO works here. Ignoring these factors means working with the wrong map.

### The Brazilian search market in numbers

Google has a strong share of search in Brazil. The table below reproduces the figures cited in the original edition of the article, from April 2026; StatCounter links are dynamic, and the original text did not specify the month covered by this snapshot. Do not treat these figures as current market shares or as directly comparable measures of total chatbot and search engine usage.

| Search engine | Market share in Brazil |
| --- | --- |
| Google | 88,72% |
| Bing | 8,56% |
| Yahoo | 2,2% |
| DuckDuckGo | 0,22% |
| ChatGPT | 0,41% |

Source: [StatCounter](https://gs.statcounter.com/search-engine-market-share/all/brazil) and [StatCounter (ChatGPT vs Google, 2025)](https://gs.statcounter.com/google-vs-chatgpt-market-share/all/brazil/2025).

Google's economic impact in Brazil also provides useful context: Google contributed R$215.4 billion to the Brazilian economy in 2024 and generated 354,000 indirect jobs through Android and other platforms, according to data from [Click P&G](https://en.clickpetroleoegas.com.br/google-movimenta-r-215-bilhoes-no-brasil-em-2024-gera-354-mil-empregos-via-android-e-anuncia-ia-para-revolucionar-compras-anuncios-e-produtividade-btl96/). This is not a secondary player.

### AI adoption in Brazil and what it means for SEO

The StatCounter snapshot cited in the original edition attributed 0.41% to ChatGPT, according to that source's methodology; this measure does not represent all use of the assistant. But traffic growth via [AI search](/en/resources/glossary/ai-search) globally was 527% in one year, according to [Semrush](https://www.semrush.com/blog/ai-seo-statistics/). This global growth does not, by itself, demonstrate the same trajectory or pace in Brazil.

What this means for people doing SEO in Brazil today: Google is still by far the priority. But preparing content to be cited by AI—using schema markup, solid E-E-A-T, and content with clear answers—already makes a difference, and will make an even bigger difference over the next two years.

A revealing figure from [AirOps](https://www.airops.com/report/influence-of-retrieval-fanout-and-google-serps-in-chatgpt): 85% of the pages ChatGPT retrieves internally are never cited in the final answer. Preparing to be cited—not just retrieved—requires more than basic indexing.

## New SEO metrics for 2026

Traditional SEO metrics still matter, but the dashboard is getting more complex. In 2026, a well-monitored strategy tracks:

**Traditional metrics that still matter:**

-   Average position by keyword
-   Total organic traffic and traffic by page
-   Organic CTR by query
-   Indexed pages vs. pages on the site
-   Domain Rating (DR) or Domain Authority (DA)

**Emerging AI metrics:**

-   Citation frequency in Google AI Overviews
-   Appearance in ChatGPT and Perplexity responses for niche queries
-   [Share of Voice](/en/resources/glossary/ai-share-of-voice) in generated responses, with the question set, period, engines, and formula documented
-   [Citation rate](/en/resources/glossary/citation-rate) vs. retrieval rate (how often you are mentioned vs. merely consulted)

**Content quality metrics:**

-   Average time on page (an indicator of actual engagement)
-   Scroll rate (how far users read)
-   Return traffic to the same content

The distinction between “discovery traffic” (users who did not know you before) and “brand traffic” (users who searched specifically for you) also becomes more relevant with AI Overviews, because AI can generate brand awareness before the click.

## SEO tools in 2026

No tool can replace strategy and human judgment. But tools can make work faster, more precise, and more scalable.

**For keyword research and competitive analysis:**

-   **Semrush:** keyword analysis, competitor rankings, site audits, and backlink analysis. A market reference.
-   **Ahrefs:** particularly strong for backlink analysis and exploring content opportunities.
-   [**Google Search Console](/en/resources/glossary/google-search-console):** free, straight from Google. Shows impressions, clicks, average position, and indexing diagnostics. AI Overviews and AI Mode are included in Web search performance, without a separate, comprehensive citations dashboard.

**For technical SEO:**

-   **Screaming Frog:** desktop [crawler](/en/resources/glossary/crawler) that maps the entire site and identifies technical issues.
-   **Google PageSpeed Insights:** free Core Web Vitals analysis.
-   **Semrush Site Audit:** automated auditing with issue prioritization.

**For content and E-E-A-T:**

-   **Google Search Console Insights:** shows how content performs with real users.
-   **Clearscope or MarketMuse:** semantic content optimization.

**For [AI visibility](/en/resources/glossary/ai-visibility):**

-   **Tropk.ai:** brings together questions, answers, and sources to analyze a brand’s presence in AI and guide content audits. Confirm in the proposal which environments and monitoring terms are available for your operation.
-   **BrightEdge:** AI Overviews analysis for companies with larger operations.

The choice of tools depends on the size of the operation and what is most limiting at the time. For those getting started, Google Search Console and a research tool can cover much of the initial diagnosis; coverage depends on requirements and subscription limits.

## How to get started with SEO in 2026

SEO has many moving parts. The most common mistake is trying to do everything at once and doing none of it well. A sequence that works in practice:

**1\\. Technical diagnosis (weeks 1–2)**

Before creating any new content, check whether the site has issues that prevent indexing. Use Google Search Console to identify coverage errors, and Screaming Frog to map redirect issues, duplicate pages, and speed problems. Fix anything blocking progress before moving on.

**2\\. Keyword research (weeks 2–3)**

Identify the terms your audience uses to find what you offer. Prioritize based on three criteria: search volume, purchase or conversion intent, and competition (there is no point trying to rank for “health insurance” with a new site). Start with long-tail terms—more specific, less competitive, and with higher conversion rates.

**3\\. Content structure (weeks 3–4)**

Organize content into clusters: one comprehensive pillar piece for the central topic, and supporting content for related subtopics. Internal links connect the two. This structure distributes authority and signals to Google that the site has real depth on the subject.

**4\\. Content creation and optimization (ongoing)**

Produce content with a real point of view, verifiable data, and depth that AI cannot replicate. Use schema markup from the start. Include an FAQ on pages that answer frequently asked questions.

**5\\. Link building (ongoing, starting in month 2)**

Start with the basics: profiles in relevant directories, mentions by partners and suppliers, and guest posts in niche publications. Move on to digital PR and original data that naturally generate citations.

**6\\. Monitoring and adjustment (monthly)**

SEO without monitoring is work without feedback. Track relevant metrics monthly and adjust what is not performing. Allow enough time for each change to show results—the algorithm does not respond in days.

The principle that ties it all together: Google wants to show its users the best possible result for every search. When your content genuinely is the best result for a specific search, the algorithm tends to recognize that.

## Frequently asked questions

### What is SEO and what is it for?

SEO stands for Search Engine Optimization. It brings together technical and editorial practices that help search engines find and understand pages and improve a site's organic presence. The work involves accessibility, useful content, links, and page experience, without guaranteeing a specific position.

### What is the difference between SEO and SEM?

SEM stands for Search Engine Marketing and can cover a search presence strategy that includes organic results and paid media. SEO is the organic side, with no charge per click on the result. Ads, such as those on Google Ads, depend on investment and auctions. The two approaches can complement each other depending on the goal and budget.

### Is SEO still relevant with AI Overviews and other AI answers?

SEO remains relevant because it helps make content accessible and understandable to search. For AI Overviews and AI Mode, Google maintains the fundamentals of SEO and requires a page to be indexed and eligible to show a snippet. Presence in these answers varies; organic rankings and AI citations should be monitored without promising equivalence.

### What is the relationship between SEO, GEO, and AEO?

SEO focuses on page discovery and organic presence. GEO, Generative Engine Optimization, aims to improve retrieval and citation in generative AI answers. AEO, Answer Engine Optimization, structures content for direct answers. Definitions of GEO and AEO overlap in the market, and all three practices share a focus on technical accessibility, usefulness, and verifiable information.

### How long can SEO take to show results?

The SEO timeline depends on the site, the issue fixed, and the competition. Google says some changes may appear within hours and others may take months; not every change leads to a noticeable improvement. Track queries and pages over a period long enough to compare trends, without treating a fixed timeframe as a guarantee.

### Does a good Google ranking guarantee a citation in ChatGPT?

A good Google ranking does not guarantee a citation in ChatGPT. Observational studies find a relationship between organic presence and citations, but the assistant selects sources based on the question, search, and synthesis. For ChatGPT search, check access for OAI-SearchBot and keep content clear and verifiable; allowing the crawler also does not guarantee selection.
